Olfactory-auditory sensory integration in the olfactory tubercle. Bar graphs of average stimulus evoked responses across 17 units in response to tone (left), odor (middle, see methods for odor) and simultaneous tone and odor presentations (right column).hus, both accessory and main olfactory systems converge in the olfactory tubercleâpresenting this structure as a âmixedâ olfactory cortex (Martinez-Marcos, 2009). These anatomical points highlight the likely role of the tubercle in the processing of odors.
Precancerous condition. A precancerous condition or premalignant condition, sometimes called a potentially precancerous condition or potentially premalignant condition, is a state of disordered morphology of cells that is associated with an increased risk of cancer. If left untreated, these conditions may lead to cancer.
Adenomatous polyps are the type of polyps associated with an increased risk of colon cancer and are sometimes referred to as pre-cancerous. Types of polyps in this category include villous adenomas, tubulo-villous adenomas, tubular adenomas, serrated adenomas and adenomatous polyps.he term pre-cancerous polyp can have two possible interpretations. One interpretation describes the evolution of the lining of the colon from normal colon cells to colon cancer. In this evolution, the patient first develops a polyp, the cells on the polyp then become atypical or dysplastic.
